Metabolite Identification
Common NameBambuterol
DescriptionBambuterol is only found in individuals that have used or taken this drug. It is a long acting beta-adrenoceptor agonist used in the treatment of asthma. It is a prodrug of terbutaline.The pharmacologic effects of bambuterol are at least in part attributable to stimulation through beta-adrenergic receptors (beta 2 receptors) of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic AMP. Increased cyclic AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.
